قیمت کالاها و نوسانات نرخ ارز: درسهایی از آزادسازی حساب سرمایه در آفریقای جنوبی

We examine the relationship between the South African Rand and the gold price volatility using monthly data for the period 1979–2010. Our main finding is that prior to capital account liberalization the causality runs from the South African Rand to the gold price volatility but the causality runs the other way around for the post-liberalization period. This finding suggests that gold price volatility plays a key role in explaining both the excessive exchange rate volatility and current disproportionate share of speculative (short-run) inflows that South Africa has been coping with since the opening up of its capital account.
